Hi there!

I don’t know how to properly answer step 1, but it looks like you already have the formula written down.

For step 2, divide 120 by 3 to find how many backpacks made in one hour, or 40 backpacks per hour.

600 backpacks = 40 backpacks/1 hour * t

Step 3: This may look complicated, but i promise it is not. All we have to do here is divide 600 by 40, or 15.

t = 15, or it will take 15 hours to make 600 backpacks.

I hope this helps!

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
